MCP3202

2.7V Dual Channel 12-Bit A/D Converter

with SPI Serial Interface

Features

Description

• 12-Bit resolution

The Microchip Technology Inc. MCP3202 is a

successive approximation 12-bit Analog-to-Digital

(A/D) Converter with on-board sample and hold

circuitry. The MCP3202 is programmable to provide a

single pseudo-differential input pair or dual single-

ended inputs. Differential Nonlinearity (DNL) is

specified at ±1 LSB, and Integral Nonlinearity (INL) is

offered in ±1 LSB (MCP3202-B) and ±2 LSB

(MCP3202-C) versions. Communication with the

device is done using a simple serial interface

compatible with the SPI protocol. The device is capable

of conversion rates of up to 100 ksps at 5V and 50 ksps

at 2.7V. The MCP3202 device operates over a broad

voltage range (2.7V - 5.5V). Low-current design

permits operation with typical standby and active

currents of only 500 nA and 375 µA, respectively. The

MCP3202 is offered in 8-pin MSOP, PDIP, TSSOP and

150 mil SOIC packages.

• ±1 LSB maximum DNL

• ±1 LSB maximum INL (MCP3202-B)

• ±2 LSB maximum INL (MCP3202-C)

• Analog inputs programmable as single-ended or

pseudo-differential pairs

• On-chip sample and hold

• SPI serial interface (modes 0,0 and 1,1)

• Single supply operation: 2.7V-5.5V

• 100 ksps maximum sampling rate at V_DD= 5V

• 50 ksps maximum sampling rate at V_DD= 2.7V

• Low power CMOS technology

• 500 nA typical standby current, 5 µA maximum

• 550 µA maximum active current at 5V

• Industrial temp range: -40°C to +85°C

• 8-pin MSOP, PDIP, SOIC and TSSOP packages
